I suggest you revisit that menu starting with using the skin.css that is closest to the colour of your menu.

If you are a novice, and want to have a fancy menu, get the coffee out, the matchsticks for under your eyes, and lots of trial and error, since customising the SolPart menu to a high level, is a challenge.

In my opinion, the simpler menu options work, and you'll find the basic menu provided with the default skins are a good place to start since they work from the beginning, instead of doing what I used to do - and I think thousands of others, copying and pasting from different places with  misinformation placed in all sorts of css files.

Get your menu in the skin.css file only,  not in the default or portal css files, and put a basic one in there for now and start making simple changes.

Then when you have specific issues you can't work out, you're able to nut out where they need to be.

Also, as a rule - I don't touch the module menu items.. they are all standard..
